To all whom it may conceive.-

Be it known that l, EMIL CAPITAINE, a cit-izen of the German Em pire, residin gat Frankfort-on-the-Main, Germany, have inventedcertain new and useful Improvements in a Pump for Liquids, of which the following is a specific-ation;

My invention relates to devices :for pumping liquids, applicable more particularly to Io gas or petroleum or other light engines, and has for its object to utilize the momentary but regularly occurring differences of speed of the periphery of the ily-wheel to move bodies of liquid by very simple mechanical r 5 devices, as will be hereinafter fully described,

and pointed out in the claims.

In the accompanying drawings, illustrating my invent-ion, Figure l is a side elevation of an engine fly-wheel, the dot-ted lines indicatzo ing the hollow interior thereof and a partition-wall in the rim thereof. Fig. 2 is a section thereof and of the crank-shaft and of feeding-in devices leading to the inferior of the hollow ily-wheel.

2 5 The vouter rim of the fly-wheel A is hollow, and the hollow annular space is divided by a partition Ct. Frein the hub of the ily-wheel a canal d leads to one side of o, into the hollow annular space, and another canal c leads 3o also from the hub to the other side of a into the hollow space. As will be seen by the drawings, the crankshaft has an annular groove CZ turned in its end, while a cylindrical hole e' is bored in the center of the 3 5 shaft some distance deeper, and by holes drilled in the side of the shaft, respectively, into d and e' these-latter are set in communication with the canals d and e, respectively.

Against the crank-shaft the non-rotating 4o body D is pressed with a sufficient springpressure to make a water-tight joint. This body D has canals d and e2, which form continuations of canals d and e', respectively, so that a continuous connection is made between the non-rotating inlet-pipe di, through the canal d and d, to the hollow space in the rim of the ily-wheel on one side of partition a and from the other side of a through canals e and e' to the outlet-pipe e4.

5o The mode of operation is as follows: lVhen the fly-wheel rotates in the direction shown by the arrow ce, then by every powerimpulse from the piston acting through the crank-shaft an acceleration of speed in this direction follows. The inertia of the water or other liquid contained in the hollow rim and the inability of the ily-wheel instantly to communicate to it its accelerated speed occasions an overpressure on the left side of the wall a and an underpressure on the right side of ot, and this 6o pressure is greater orslnaller according as the acceleration of the fly-wheel is greater or smaller, and it follows that the water in the hollow space of the rim under this pressure will be forced through the canals e and e and 6 5 out of the pipe e4, and likewise will be sucked again through the pipe d4 and canals CZ and CZ into the rim of the ily-wheel. By the now following slowing down of the speed of the ilywheel, (as a consequence of the load on the 7o motor or as a consequence 0f the work lostin the motor itself, or by both togethelg) the water in the rim having in the meantime acquired part of the acceleration, it will for a moment, and before the next power impulse from the piston, possess a slightly higher velocity than the wheel, and the water would therefore rush back in the opposite direction to that described above, and to prevent this I place a check-valve V in the pipe d, as 8o shown.

The degree of effect of this pump is of course dependent on the irregularity of speed of iiywheel, and this again is dependent on the proportion of the rotating mass of the ily-wheel to the force of the power impulse, or otherwise also on the proportion of the mass of the ily-wheel to the rapidity of the periodicallyoccurring explosion. Therefore the application of this pump is more particularly adapt- 9o ed for circulating cooling-water in the motors for boats, for instance, where a comparatively small and light fly-wheel must of necessity be used, but it can also be used entirely for power-pumping in connection with a motor.

I-Iaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a rotating flywheel having within its rim an annular cham- 1 oo ber formed with a partition-wall and also having canals or passages leading from opposite sides of said Wall through the spokes, to openings in the interior of the hub, a shaft upon which said Wheel is mounted having openings or passages in its end registering with the oriices in the hub, a non-rotating body having inlet and discharge openings arranged to register with the respective passage-Ways in the shaft and Wheel-hub, and with means, such as a check-Valve, to alternately open and close said inlet-port; substantially as described.

2. A fiuid-pump comprising a rotating iiy- Wheel having a rim, a chamber in its rim, a spoke and hub with passages communicating respectively with opposite end portions of said chamber, a shaft having passages in its end registering With the passages in the wheel, a non-rotatin g body having inlet and outlet passages, and means to alternately open and close the inlet-passage, the said last-inentioned passages operating as inlet and discharge ways for liquid respectively sucked into and discharged from the Wheel-rim recesses by means of the momentary but reg ularly occurring diiferences of speed in its rotation; substantially as described.

3. A rotary pump Afor liquids comprising a iiy-Wheel having an annular passage in ts rim, said passage having a partition wail across it, canals d and e in the spoke and hub leading to said annular passage, a shaft hav-- ing passages cl' and e communicating therewith respectively@ non-rotating body D having canals cl2 and e2 arranged to communicate with the respective passages in the shaft, and with inlet and discharge openings and means such as check-Valve V operating to alternately open and close the inlet-opening; substantially as described.

In testimony whereof I have signed ny name to this specification in the presence or' two subscribing Witnesses.
